Be interesting to see a similar map of Coventry.
As for Dresden etc, one might argue a bit less marching into the Sudetenland, clanking through Poland, sneaking round the side of the Maginot Line and so forth and the whole mess could have been avoided, and Europe might not be as impoverished as it is. But of course then we'd get into the whole WWI peace treaty thing and yadayadayada back to Charlemagne.
But if it hadn't happened, Britain wouldn't have gone bankrupt trying to hold the line.
I was born and lived for five years in Hillfields, Coventry. I well remember the landscape of bomb sites pierced by completely soulless blocks of flats. What a view could be had from them - rubble and weeds. There was no money for clean-up or development, you see.
Most commodities were still rationed two years before I was born. My dad needed a permit for two tongue-and-groove floorboards before he could buy them. Remember that next time you are in the DIY centre. Britain's economy was wrecked by WWII, and it never recovered.
Also, if the pesky Hun hadn't mobilized with extreme prejudice, the Americans wouldn't now be able to say they came in to save the day. Don't blame the Americans for boasting, blame the buggers who pulled a knife and yelled "come on have a go if you think you're hard enough!" and provided the opportunity.
